FAUCET.

SPECIFICATION forming part of Letters Patent N 0. 641,601, dated. January 16, 1900.

Application filed January 10,1899. Serial No. 701,702. (No model.)

To all whom it may concern:

Be it known that I, GEORGE O. MILLER, a citizen of the United States, residing at North Tonawanda, in the county of Niagara and State of New York, have invented certain new and useful Improvements in Faucets,of which the following is a specification.

My invention relates to an improved faucet, and particularly to the valve-seat construction thereof; and the main object of the invention is to provide a detachable seat portion that can easily be removed and replaced when injured or worn. It also relates to certain other details of construction, all of which will be fully and clearly hereinafter described and claimed, reference being had to the accompanying drawings, in which Figure 1 represents a side sectional elevation, showing the interior construction of the faucet. Fig. 2 represents a detached top View of the detachable seat portion. Fig. 3 represents a detached side sectional elevation of the detachable seat portion, illustrating a modified form thereof, rendering it reversible.

Referring to the drawings in detail, in which like numerals represent like parts, 1 designates the body of the faucet,which is provided with the usual screw-threaded end 2 for connection to the water pipe and spout 3.

The interior of the faucet-body is divided into two compartments by means of the partition 4, which is provided with a screwthreaded opening 12, into which the short tubular portion 5, forming the detachable valveseat, is inserted. This annular valve-seat can be formed with one of its ends 6 screw-threaded, as in Fig. 1, or with both screw-threaded, as in Fig. 3, the latter being preferable, as it enables the seat to be reversed, if desired. The seat is provided with a central outwardlyextending peripheral enlargement or flange 7, and the upper portion 11 of the opening in the partition is enlarged sufliciently to provide a seat for the same. (See Fig. 1.) The seat is also provided with small projections 8, extending inwardly from the interior thereof,

' against which the sides of a screw-driver or other suitable instrument may be caught to rotate the seat, and thus insert it in or remove it from the opening in the partition. The faucet-body is also provided with the usual upper substantially vertical tubular portion 9, which is internally screw-threaded, and a top cap 10 is adapted to be inserted and screwed into said tubular portion. The top cap is provided with acentral opening,which is smooth in its upper portion and screwthre'ade'd in its lower portion, (see Fig. 1,) and the stem or plunger 13 is provided with a screw-threaded portion 14 of substantially the same lead and is adapted to be screwed into the lower portion of said opening, the upper smooth-surfaced portion of the opening being sufficiently large to allow the stem to pass freely through. The plunger is provided at its upper end with the usual handle orhand-wheel 15 and near its lower end, below the screwthreaded portion 14, with an enlargement 16, forming a shoulder or abutment. Below the enlargement 16 the stem or plunger is reduced sufficiently to allow it to pass freely through the opening in the valve-seat, and an upper washer 17, of leather or other suitable material, is secured upon said reduced portion with its upper face in contact with the abutment. A lower leather washer 18 is also secured upon the extreme lower end of the plunger by means of the metallic washer 19 and screw 20. A screw-threaded opening 21 is also provided in the faucet-body substantially vertically below the lower washer, and is closed by the screw-cap 22, thus providing means for the easy dismounting of the lower washer and its supports. The lower portion of the tubular portion is reduced sufficiently to provide a seat for a metallic washer 23, and a leather washer 24 is supported between said metallic washer and the lower end of the top cap, thus providing a packing for the plunger.

With my improved device the water can be shut ofi by turning the handle in either direction, as the upper washer will come in close contact with the upper face of the valveseat and close the opening in the partition when it is turned in one direction, and the lower washer will come in contact with the lower face of the valve-seat and also close the opening when turned in-the opposite direction. When it is desired to allow the water to flow, the plunger should be rotated to bring the washers in substantially the position shown in Fig. 1. By this means two practically independent valve-closures are provided, and the danger of damaging the faucet by screwing it too far open is obviated, as the water is shut 01f by rotating the plunger too far in either direction.

With a little alteration the ordinary faucets now on the market can be provided with my improved detachable and reversible valveseats and their value and lives greatly increased and lengthened thereby.

The faucet can be easily dismounted by removing the bottom cap, detaching the lower washer and its supports from the lower end of the plunger, and unscrewing the upper cap and removing it from the vertical tube. The valve-seat can then be removed by any suitable instrument, as hereinbefore described.

I claim as my invention A faucet having a tubular screw-threaded extensionrfor connection to the source of water-supply, a spout and an upper and lower screw-threaded opening and having its interior divided into two compartments by a partition provided with a screw-threaded opening enlarging into an upper countersunk portion, a double-faced valve-seat having screwthreaded ends screwing into the screw-threaded opening in the partition and a central flange seating in the countersunk portion, a plunger having a screw-threaded portion, a hand-wheel and upper and lower washers adapted to contact with the faces of the valveseat, a hollow cap having exterior screwthreads adapted to engage in the upper screwthreaded opening and interior screw-threads engaging with the screw-threaded portion of the plunger, and a lower screw-cap adapted to close the lower screw-threaded opening, as

set forth.
